Keep in mind that clock is a young package, with plenty of room to grow. You can stick with one or the other, or use them together, as there are no name conflicts between the two. As of now, we consider clock to be an alternative to lubridate. Lubridate will never go away, and is not being deprecated or superseded. While lubridate is solely focused on working with R’s native Date and POSIXct classes, clock goes many steps further with types such as: date-times without an implied time zone, nanosecond precision date-times, built-in granular types such as year-month and year-quarter, and a type for representing a weekday. As you’ll see in the following sections, clock tries extremely hard to guard you from unexpected problems that can arise from these two complex concepts.Īdditionally, clock provides a variety of new types for working with date-times. One of the primary motivations for creating clock was to improve on lubridate’s handling of invalid dates and daylight saving time. lubridate has powerful capabilities for working with this kind of data. If you’ve ever worked with dates or date-times in R, you’ve probably used ![]() Library ( clock ) library ( nycflights13 ) library ( tidyverse ) library ( lubridate ) Logo Currently, operations on POSIXct have roughly the same performance between clock and lubridate (clock’s performance with POSIXct will improve greatly in a future release, once a few upstream changes in date are accepted). In general, operations on Dates are much faster with clock than with lubridate. Requires explicit handling of invalid dates (e.g. what date is one month after January 31st?) and nonexistent or ambiguous times (caused by daylight saving time issues).ĭate library, which provides a correct and high-performance backend. High level API for Date and POSIXct classes that lets you get productive quickly without having to learn the details of clock’s new date-time types. ![]() Provides a new family of date-time classes (durations, time points, zoned-times, and calendars) that partition responsibilities so that you only have to think about time zones when you need them. In addition to these tools for manipulating date-times, clock provides entirely new date-time types which are structured to reduce the agony of working with time zones as much as possible. It is packed with features, including utilities for: parsing, formatting, arithmetic, rounding, and extraction/updating of individual components. clock is a new package providing a comprehensive set of tools for working with date-times. We’re thrilled to announce the first release ofĬlock.
